Airtec Double Insulation 1.05 x 25m 4.3 5 23 23
hardly effective I bought this for 2 purposes: to supplement cellotex board in a narrow space of 3" where i used 2" cellotex + a layer of airtec and also as a wrap over screwfixes economy pipe insulation (13mm) used on 15mm and 22mm heating pipes under floors (fully taped joints with aluminium foil). Airtec is stated to be equivalent of 55mm polystyrene! WOW! Really? From something only a few mm thick? Too good to be true? YES! I did some tests because when my heating was on the double insulated pipes felt WARM! Now with 13mm foam sleeve and 55mm polystyrene no detectable heat should escape! So I used a digital thermometer probe just resting on top of the outer surface of the airtec: Heating off in cold house = 11.2c Heating fully on and hot pipes = 21.6c Water temperature in the pipe = 52-54c So significant heat loss through the foam sleeve and outer aitrtec wrap - a rise of 10c! This stuff is basically bubble wrap with silvered surfaces. At £100 a roll i think i wasted my money and time putting it round my pipes. An email to their technical line was never answered so no aftersales service either! How can anything so thin which is basically bubble wrap perform like 55mm polystyrene! The silver coating would reflect some heat, but there is very little radiated heat from pipes or radiators (which should really be named convectors) In my view this product is hardly effective and therefore a waste of money. Very disappointing! 28 Jan 2015
Easy to fit I have just purchased a roll of Airtec Double Insulation 1.05 x 25m to line the rafters of storage space in my attic. The roll was very easy to cut to size and stsaple in place. It is too soon to comment on its insulation quality. 8 Jan 2015
Impressed but wondering I was given this product and used it without knowing what it was. Hence I stuck it on a cold wall with tiling adhesive and then wallpapered over it! As soon as it was up we noticed the difference in the room, it was amazing. I was wondering about using more of it on another cold wall when I found out what the product is. No mention of sticking it to walls! Have I done OK with it? Could I do the same again? I would be grateful for any advice! As I say, I think it has worked very well where it is - I just hope it doesn't decide to fall off! 10 Dec 2014
Nice insulation Used a layer of this (with 25mm airgap) above thermalboard and plasterboard in a sunroom. Much simpler and cleaner than mineral wool to install. Will use again. 21 Nov 2014
